727 vs 904
They're not my legs. Good parts do cost money; especially for a 904; because it needs a ton more of them than a 727. Mis-quote: "it's weakness is that it only hold 3 clutches"...there, for what good it'll do..
We are having communication breakdown. What I meant to say using a bad combination of words, is that if a guy wanted to build a 727 say to handle 700 horse, and he already had a 383 3 clutch 727, I would not tell him not to use it. I would explain to him that the stock drum, regardless of it factory clutch count, should not be used for the intended application. By default every aftermarket performance drum is usually manufactured for an increased clutch count. It makes no sense for them to manufacture a high dollar
Explosion proof drum for $700.00 that holds 3 clutches.
IMHO a responsible performance 727 builder should be making his customer aware of this. Not waiting till his stock 6 clutch drum blows up and he loses a leg or his car catches fire and burns to the ground. Hot trans fluid will indeed burn. I've seen it on a 12 second street car. Now having said all this and without a whole lot of trick
Potentially unnecessary parts, you could still be at $2,000.00
From that perspective, a 904 with a stock 5 clutch drum from the wreckers is much cheaper to build and safer with its factory riveted
Roller clutch and a stock drum that does not blow up. The .15 performance gain the 904 has is a bonus.
